sTITcHLnss EYE TAPE.

Application vfiled February 23, 1927. Serial No. 170,245.

My invention relates to stitchless, rivetless eye tapes in which the eyes are inserted into the tape fabric without sewing or riveting and in which the pull comes against a fold in the fabric to give strength to the structure, in which the bases of the eyes are covered, concealed and protected and in which the various plies making up the tape are secured together by the eyes themselves without sewing as has heretofore been customary. My invention is particularly applicable to standard eyes but special forms may be used without departing vfrom my invention.

There are two kinds of hook and eye tapes in use at the present time. First, the type in which the bases of the hooks or eyes are riveted to the tape. This lmethod of production requires wire bending machines to make the hooks or eyes, a machine to form the rivets and a machine to assemble the hooks or eyes, the rivets and-the tape. The hooks or eyes and rivets are' generally plated after manufacture and a woven fabric tape with selvage edges is generally used. In the second, or sewed type the hooks or eyes are formed in wire bending machines and plated and a sewing machine provided with feeding and folding attachments sews them to a strip of fabric. The wire bending machines now in use have an output of about 400 hooks or eyes a minute.

In producing hook or eye tape embodying my improvement the separate assembling machine, the plating plant, the rivet making machine and the special sewing machine are eliminated and strips of. piece goods can be used as the tape. The hooks or eyes are formed of plated wire in the wire bending machine and immediately assembled and attached to the tape in practically onc operation and at a production out put of 300 a minute as compared with an output of 100 a minute for riveted tape and 7 5 a minute for the sewed hook or eye tape, making the cost of production of my improved hook or eye tape very low in comparison as well as greatly increasing the output with a given number of machines and employees.

In the drawing I have shown one form of eye tape,the hook tape being reserved for a separate application. Fig. l is a faceview of an eye tape embodying my invention; Fig. 2 a back view of the structure of l, partly broken away; Fig. f 3 a cross-section of the structure of Fig.' l on the line 3 3 thereof; Fig. 4' a view of the folded tape ready to receive the eyes; Fig. 5 a view of the partly formed eye; and Fig. 6 a sectional view of the structure of Fig. l on the line 6 6 thereof. All the figures are Xaggerated to more clearly show the invention.

In making the eye tape a strip of fabric is first folded as shown in Fig. 4 with the outer plies 1 and 2 and the inner plies 3 and 4 betweenthem. The shanks l0 of the partially formed eyes e are then pushed through all the plies on the line a-n, Fig. 4, and the base loops Il formed on the back. The plies 2 and 4 are` theny partially turned over the base loops as shown in Figs. Sand 6 so that the operative portion of the eye is exposed on the face of the tape and vthe base loops 1l lie between the folds 2-2 which resist the pulling strain on the eye when in use.

VBy this construction all sewing and riveting is eliminated and the various plies of fabric are held together by the wire of the eye itself. As my eye tape has no stitching in its make up it always lies fiat and straight and is more easily handled by the operators in sewing it to a garment. V

For convenience the ply 1 will be termed they face ply, the ply 3 the return ply, the ply 2 the third ply, the ply 2 the fourth ply, the ply 4 the fifth ply and the ply 4 the sixth ply.

l. Stitchless hook or eye tape comprising a strip of'fabric folded on itself to form av face ply and a bottom ply and intermediate inner folds between the two; a fasteningH member provided with base loops passing through the face ply and certain of the inner plies with the base loops lying between inner alies, other plies extending over and concea ing the base loops, said fastening member being the sole means for securing the various plies together.

2. Stitchless hook or eye tape comprising a strip of fabric one side being folded on itself to form a face ply, a return ply thereunder, the other side being folded inwardly Qover the return ply to form a third ply,

then outwardly to form a, fourth ply, then inwardly again to form a fifth ply and finelly under the third ply to form a sixth ply and an eye member provided with base loopsV-passin through the face, return, third the third and fourth plies, said eye member plies together.
